Note 1: File Type ranges other than the default value shown in 'File Type # Min' are 8-999.
Note 2: Address range for I & O are in rrg (rr=rack num., g=group num.) Address Max for S is dependent on the
PLC.
Note 3: Bits may wrap into other words. EX: B3:5/41 = B3:7/9 Bit format is Decimal.
Note 4: Integer types (range –32768 to 32767) may be configured as unsigned (range 0 – 65535). Data format is
16 bit Decimal.
Note 5: These are system variables. Use caution when writing to S variable types.
Note 6: O and I bits can use octal addressing by adding 'o' to the bit address. EX: I1:2/o17.
Note 7: Default format for I/O is Octal words and Decimal Bits
